The video tutorial explains the concept of integration by using a scenario where Johnny drops a coin from a building. It covers the basics of gravity and acceleration, defining variables and axes, and the integration process to find velocity and displacement. The tutorial concludes with calculating the coin's velocity and displacement after five seconds.
